How to add custom statistics in Grinder - jython

In Grinder we'd like to add customized statistics
grinder.statistics.registerSummaryExpression("connTimeout", "userLong0")
grinder.statistics.forCurrentTest.addLong("userLong0", 1)
And it seems to be successful as we can get the customized field in Grinder out file
The problem is that the value of that statistics is always 0
Here is the complete script implemented by Jython
# -*- coding: utf-8 -*-
from net.grinder.script.Grinder import grinder
from net.grinder.script import Test
from com.netease.cloud.ndir.performance import Query
from com.netease.cloud.ndir.performance import QueryReturnCode
def writeToFile(text):
filename = "response.log"
file = open(filename, "a")
file.write(str(text) + "\n")
file.close()
ndir_client = grinder.getProperties().getProperty("ndirClient")
query_file = grinder.getProperties().getProperty("queryFile")
request = Query("grinder.properties", query_file)
grinder.statistics.registerSummaryExpression("connTimeout", "userLong0")
grinder.statistics.registerSummaryExpression("readTimeout", "userLong1")
grinder.statistics.registerSummaryExpression("code!=200", "userLong2")
grinder.statistics.registerSummaryExpression("docs=[]", "userLong3")
grinder.statistics.registerSummaryExpression("unknown", "userLong4")
class TestRunner:
def __init__(self):
grinder.statistics.delayReports=True
def initialSleep(self):
sleepTime = grinder.threadNumber * 20 # per thread
grinder.sleep(sleepTime, 0)
def query(self):
if ndir_client == "true":
query = request.randomQueryByNdirClient
else:
query = request.randomQueryByHttpGet
try:
result = query()
except:
writeToFile("exception")
grinder.statistics.forCurrentTest.addLong("userLong4", 1)
grinder.getStatistics().getForCurrentTest().setSuccess(False)
return
if result == 0:
grinder.getStatistics().getForCurrentTest().setSuccess(True)
return
elif result == 1:
grinder.statistics.forCurrentTest.addLong("userLong0", 1)
grinder.getStatistics().getForCurrentTest().setSuccess(False)
return
elif result == 2:
grinder.statistics.forCurrentTest.addLong("userLong1", 1)
grinder.getStatistics().getForCurrentTest().setSuccess(False)
return
elif result == 3:
grinder.statistics.forCurrentTest.addLong("userLong2", 1)
grinder.getStatistics().getForCurrentTest().setSuccess(False)
return
elif result == 4:
grinder.statistics.forCurrentTest.addLong("userLong3", 1)
grinder.getStatistics().getForCurrentTest().setSuccess(True)
return
else:
grinder.statistics.forCurrentTest.addLong("userLong4", 1)
grinder.getStatistics().getForCurrentTest().setSuccess(False)
return
request = Test(120, 'query').wrap(query)
def __call__(self):
if grinder.runNumber == 0:
self.initialSleep()
self.request(self)

I suspect the problem is that you are marking tests as failed, but expecting the statistics to appear in the summary. Only successful tests are accumulated into the summary statistics.
Try registering data log expressions as well
grinder.statistics.registerDataLogExpression("connTimeout", "userLong0")
grinder.statistics.registerDataLogExpression("readTimeout", "userLong1")
grinder.statistics.registerDataLogExpression("code!=200", "userLong2")
grinder.statistics.registerDataLogExpression("docs=[]", "userLong3")
grinder.statistics.registerDataLogExpression("unknown", "userLong4")
Then you'll at least see the values in the data log file of the worker process.

Error while validating User Input in Python

I am having problem validating the user input (I am asking user if they wish to continue with the program of calculating factorial). The code is as follows: (User input validation is towards the end of the main function and I have not included the factorial function)
def main():
valid_inp = False
usr_continue = True
while usr_continue:
while valid_inp == False:
usr_inp = int(input('Please ENTER a number: '))
if usr_inp < 0:
print('ERROR, INVALID INPUT')
else:
valid_inp = True
continue
result = factorial(usr_inp)
print(str(result) + '\n')
con_inp = str(input('Would you like to continue ? '))
if con_inp == 'Y' or con_inp == 'y':
usr_continue
elif con_inp == 'N' or con_inp == 'n':
print('Goodbye...')
break
main()
Make a function that only returns on valid input. Use an exception handler to deal with bad integer input, then validate the integer is the range you want:
from math import factorial
def get_nonnegative_integer(prompt):
while True:
try:
val = int(input(prompt)) # bad input for int such as "abc" will raise ValueError
if val >= 0: # good input will be range-checked
return val
else:
print('enter a number >= 0')
except ValueError:
print('invalid input for integer')
def main():
while True:
usr_inp = get_nonnegative_integer('Please enter a number: ')
result = factorial(usr_inp)
print(result)
con_inp = input('Would you like to continue(Y/n)? ').upper() # default Yes
if con_inp.startswith('N'):
print('Goodbye...')
break
main()

Twisted will not send data back only if I use async DB ops

After struggling with inlineCallbacks and yield of twisted/txredisapi, I can save my data into redis. Thanks to author of txredisapi. Now I met a new issue, socket server will not send back to client before/after saving into DB.
Twisted offers simple socket server as following:
from twisted.internet import protocol, reactor
class Echo(protocol.Protocol):
def dataReceived(self, data):
self.transport.write(data) ### write back
class EchoFactory(protocol.Factory):
def buildProtocol(self, addr):
return Echo()
reactor.listenTCP(8000, EchoFactory)
recctor.run()
My code is similiar, only with additional DB ops.

And clip of my client, which is a simple client:

try:
s.connect((host, port))
s.sendall(''.join(packet))
data = s.recv(1024)
s.close()
print 'Received', repr(data)
except socket.error, err:
print "Remote socket is not available: %s"%str(err)
sys.exit(1)
The current status is:
If disable #defer.inlineCallbacks and yield opertions of dataReceived(), both self.transport.write() inside of connectionMode() and dataReceived() can output data to clients.
If we enabled #defer.inlineCallbacks and two yield DB ops of SQL/Redis, then self.transport.write() inside of connectionMode() prints every 5 connections, and dataReceived() will not output any data to clients.
the debug print statements will print on log regardless of #defer.inlineCallbacks anyway.
I was told that dataReceived() should not be #defer.inlineCallbacks. But it doesn't change anything if I removed that decoration.
I am thinking if gevent can help me out of this unpredicted behavior. I am twisted into an endless tornado, cyclone .....
Anyone who has similiar experience, please help me. Thanks.
By changing function as following, the code works.
#COMMENT OUT decorator of #defer.inlineCallbacks
def dataReceived(self, data):
global dbpool, rcs
(self.snrCode,rDat,pDat) = getDataParsed(data)
if self.snrCode == None or rDat == None or pDat == None:
err = "Bad format"
else:
err = "OK"
print "err:%s"%(err) # debug print to show flow control
self.err = err
self.transport.write(self.snrCode)
self.transport.write(self.err)
self.transport.write(rDat)
self.transport.write(pDat)
self.transport.loseConnection()
if self.snrCode != None and rDat != None and pDat != None:
self.saveRealTimeData(rcs, rDat)
self.savePeriodData(dbpool, pDat, conf)
# Removing yield before DB ops
print "err2:%s"%(err) # debug print to show flow control
#defer.inlineCallbacks
def saveRealTimeData(self, rc, dat):
print "saveRedis"
key = "somekey"
val = "somedata"
yield rc.set(key,val)
yield rc.expire(key,30)
#defer.inlineCallbacks
def savePeriodData(self,rc,dat,conf):
print "save SQL"
query = "some SQL statement"
yield rc.runQuery(query)
If we keep #defer.inlineCallbacks and yield in dataReceived. The connection is closed before second DB op. Therefore no data is output to connection. Maybe is caused by inlineCallbacks decorator.
By removing this, the flow control is simple and straightforward.
However, I still can get why I can not add inlineCallbacks if there are two deferred DB ops. This time they don't need deferred?

how to get tornadoredis listen value

I want to write a chat demo with tornado and redis. I use redis subscribe , but what I wrote is not work . when I run the code , iterm output
listening 8000
GroupChat here
getMsg here
None
None
And I PUBLISH testc helloword in redis-cli, iterm output:
[I 150401 18:30:57 web:1825] 304 GET /groupchat?key=testc (127.0.0.1) 2.40ms
Message(kind=u'message', channel=u'testc', body=u'helloword', pattern=u'testc')
I just want to get the Message in GroupChat.get , but I get None. anyone help me?
GroupChat code is here :
class GroupChat(tornado.web.RequestHandler):
def initialize(self):
print 'GroupChat here'
self.c = tornadoredis.Client(host=CONFIG['REDIS_HOST'], port=CONFIG['REDIS_PORT'], password=CONFIG['REDIS_AUTH'])
self.channelMsgModel = channelMsgModel(self.c)
#tornado.gen.coroutine
def get(self):
try:
key = self.get_argument('key')
info = yield self.channelMsgModel.getMsg(key)
print info
self.finish(info)
except Exception, e:
print e
pass
channelMsgModel code is here :
import tornado.gen
class channelMsgModel :
timeout = 10
def __init__(self, redisobj):
self.redisobj = redisobj
#tornado.gen.coroutine
def getMsg(self, key):
print 'getMsg here'
yield tornado.gen.Task(self.redisobj.subscribe, key)
info = self.redisobj.listen(self.on_message)
print info
raise tornado.gen.Return(info)
def on_message(self, msg):
if (msg.kind == 'message'):
print msg
return msg
elif (msg.kind == 'unsubscribe'):
self.redisobj.disconnect()
# raise tornado.gen.Return(False)
Use a toro.Queue (which will be included in Tornado itself in the upcoming version 4.2):
class channelMsgModel:
def __init__(self, redisobj):
self.redisobj = redisobj
self.queue = toro.Queue()
#gen.coroutine
def getMsg(self, key):
yield gen.Task(self.redisobj.subscribe, key)
self.redisobj.listen(self.on_message)
info = yield self.queue.get()
raise tornado.gen.Return(info)
def on_message(self, msg):
if (msg.kind == 'message'):
self.queue.put_nowait(msg)
elif (msg.kind == 'unsubscribe'):

Python twisted, reactor.callLater() not defering

The following code snippet is from a python poker server. The program works except when trying to delay the start of a tourney when a reactor.callLater is used.
The variable "wait" gets its integer from an xml file which has a setting of "60". However the delay is never implemented and the tourney always starts immediately. I am not very familiar with python or twisted just trying to hack this into working for me. One thing however from my perspective is it seems that it shouldn't work given that I can't see how or where the variable "old_state" gets its value in order for the code to properly determine the states of the server. But perhaps I am mistaken.
I hope that someone familiar with python and twisted can see what the problem might be and be willing to enlighten me on this issue.
elif old_state == TOURNAMENT_STATE_REGISTERING and new_state == TOURNAMENT_STATE_RUNNING:
self.databaseEvent(event = PacketPokerMonitorEvent.TOURNEY_START, param1 = tourney.serial)
reactor.callLater(0.01, self.tourneyBroadcastStart, tourney.serial)
# Only obey extra_wait_tourney_start if we had been registering and are now running,
# since we only want this behavior before the first deal.

I have discovered that this code has several imported files that were in another directory that I did not examine. I also made a false assumption of the purpose of this code block. I expected the function to be arbitrary and delay each tourney by n seconds but in practice it implements the delay only when a player forgets about the game and does not show up for it. These facts were made clear once I examined the proper files. Lesson learned. Look at all the imports!
